Final answer:
Calcium chloride does not influence the workability of concrete; it is an additive used to accelerate setting time, particularly in cold weather.
Step-by-step explanation:
The factor that does not influence workability of concrete from the given list is Calcium chloride. Workability of concrete is a measure of how easily the concrete can be mixed, placed, and finished in construction works. Factors that affect workability include the amount of entrained air, concrete consistency, and the quantity of cement. Calcium chloride is actually a setting accelerator that is sometimes added to concrete to reduce the time for initial set, particularly in cold weather, and is not directly related to its workability.
